Gemini was the second major project in the United States' manned spaceflight effort. This title examines each two-man mission to test equipment and techniques to be used by the later Apollo missions to the Moon. These include docking maneuvers and spacewalks, all untested before the Gemini missions. Also examines the parallel space exploration efforts of the Soviet Union during this period.
